Unable to create EDGE in Orientjs

Question

I'm working with OrientJS and I am trying to create an edge between two nodes. Until some days ago, all worked fine with the script below:

module.exports.insertRelatedToAssociation = (nodeFrom, nodeTo) => {
    db.create('EDGE', 'RelatedTo')
        .from(nodeFrom).to(nodeTo)
        .one()
        .then(function (result) {
             return (result !== undefined)
         })     
}

But now, I suddenly receive this error message everytime I run the script:

com.orientechnologies.orient.core.sql.OCommandSQLParsingException: Error parsing query:
CREATE EDGE RelatedTo FROM #29:5
     ^
Encountered " <CREATE> "CREATE "" at line 1, column 1.

Maybe, OrientDB changed its parser, but I found nothing about it on the GitHub Wiki (https://github.com/orientechnologies/orientdb/wiki/OrientDB-2.2-Release-Notes#2226---august-16-2017).

Note: I am running the orientdb-community-importers-2.2.24. The same is with the version 2.2.26.

Answer 1

I found the error. It simply was that the parameter nodeFrom was undefined. So passing undefined to db.create('EDGE','RelatedTo).from(undefined).to(nodeTo) produce that error!
